How do you do systems of two equations? Problem: y=-3x+4, y=3x-2

juin [17]

I assume you are trying to solve for each variable. if thats the case you want to use one equation to solve for y and then plug the y value into the next variable
Problem: y =-3x=4 so -3x+4=3x-2
x=1
plug x value into one of the equations
y=3(1)-2
y=1

PLEASE HELP RN

yulyashka [42]

Step-by-step explanation:

y = -9x - 45 -5

y = -9x - 50

slope = x coefficient = -9

we can use the point where

x = 0

y = -50

P1 (0, -50)

and when y = 0

-9x = 50

x = -50/9

P2 = (-50/9 , 0)

Jack is mowing a lawn that has a shed. needs to know area of lawn to mow. dimensions of yard are 5x by 13 x-4 . she'd are 2x by

Elena-2011 [213]

The diagram of the lawn and the shed is shown below.

The area of the lawn needed to be mowed equals to the area of the yard minus the area of the shed

The area of the yard = $(5x)(13x-4) = 65 x^{2} -20x$
The area of the shed = $(2x)(2x+4)=4 x^{2} +8x$

The area of the lawn = $65 x^{2} -20x-(4 x^{2} +8x)$
The area of the lawn = $65 x^{2} -20x-4 x^{2} -8x$
The area of the lawn = $61 x^{2} -28x$
